This book contains an introduction to other aspects of contact mechanics as
well, such as finite element methods, plastic deformation, wear, corrugation,
tyres, noise and lubrication. These topics were presented in an advanced course
on contact mechanics held in Udine, Italy in 1999.

Kalker's book gives a comprehensive mathematical
formulation of the frictional contact problem, an overview of solution
approaches, and a detailed description of the variational approach.

In 2009 the rolling contact model was
extended to avoid certain irregularities in the numerical results,
particularly related to the treatment of the leading edge of the contact
area. This work was extended by van der Wekken in 2017.
